1、chapter 13 stock market analysis 1.although corporate earnings may rise by 12 percent next year, that information by itself is not sufficient to forecast an increase in the stock market. the market level is a product of both corporate earnings and the earnings multiple. the earnings multiple must li

2、kewise be projected since it is not stable over time. 2.student exercise 3.the investor can improve his net profit margin estimate by working from the gross margin down to the net profit margin. by this procedure, the investor explicitly considers each major component that affects the net profit mar

3、gin. this level of analysis provides insights into the components which do not behave consistently over time. also, the gross profit margin should be easier to estimate since it has the lowest level of relative variability. 4.the effect of a decline in capacity utilization should be a decline in the

4、 aggregate profit margin, all else the same, because it will mean greater overhead and depreciation per unit of output. also more fixed financial charges per unit. 5.the increase in hourly wages of 6 percent will, all else held equal, cause the operating margin to decrease. in addition to the estima

5、te of the changes in the hourly wage rate, an estimate of the productivity rate change is also needed to forecast the unit labor cost change. the relationship is: % hourly wages - % productivity = % unit labor cost 6.7.0- 5.0 = 2.0% increase in the unit labor cost. the unit labor cost is negatively

6、related to the profit margin. this increase would, holding other factors constant, decrease the aggregate profit margin. because it is a low rate of increase, the effect on the profit margin should be small. 7. 7(a).an increase in the roe with no other changes should cause an increase in the multipl

7、e because it would imply a higher growth rate. an important question is, how was the increase in roe accomplished? if it was due to operating factors (higher asset turnover or profit margin) it is positive. if it was due to an increase in financial leverage, there could be some offset due to an incr

8、ease in the required rate of return (k). 7(b).increase, because this will increase earnings growth by raising equity turnover. it could also cause a decrease because it will increase the financial risk and, thus, the required k. 7(c).decrease, because this will increase growth and therefore raise th

9、e real rfr. it could also reduce inflation, which would decrease the nominal rfr, causing the multiplier to rise. 7(d).increase, because a decrease in the dividend payout rate increases the retention rate, raising the growth rate. it could also cause a decrease because it reduces the next periods di

10、vidends. 8.both the present value of cash flow approaches and the relative valuation ratios approach require two factors be estimated: (1) required rate of return on the stock, because this rate becomes the discount rate or is a major component of the discount rate, and (2) growth rate of the variab

11、le used in the valuation techniques, such as, dividends, earnings, cash flows or sales. 9.the ddm assumes that (1) dividends grow at a constant rate, (2) the constant growth rate will continue for an infinite period, and (3) the required rate of return (k) is greater than the infinite growth rate (g

12、). therefore, the infinite period ddm cannot be applied to the valuation of stock for growth companies because the high growth of earnings for the growth company is inconsistent with the assumptions of the infinite period constant growth ddm model. a company cannot permanently maintain a growth rate

13、 higher than its required rate of return, because competition will eventually enter this apparently lucrative business, which will reduce the firms profit margins and therefore its roe and growth rate. therefore, after a few years of exceptional growth (a period of temporary supernormal growth) a fi

14、rms growth rate is expected to decline. eventually its growth rate is expected to stabilize at a constant level consistent with the assumptions of the infinite period ddm. 10.nominal gdp growth is equal to real gdp growth plus the rate of inflation. from exhibit 13.27, we find nominal gdp for the un

15、ited kingdom for 2003 can be estimated as 2.8% (real gdp) + 2.6% (inflation) = 5.4%. for japan, the estimate is 1.0% + (-0.7%) = 0.3%. 11.the nominal rate of interest is approximately the expected real rate of interest plus the expected rate of inflation. further, the real rate of interest can be ap

16、proximated by the expected real growth rate in gdp. from the numbers in exhibits 13.27 and 13.29, we see that the united states has a higher real growth rate, both currently and forecasted, as well as a higher expected rate of inflation than japan. both factors help explain the higher current interest rate in the u.s. relative to japan. chapter 13 answers to problems 1.using only the graph and drawing a line over from ten percent to the line of best fit and down to the horizontal percent change indicates an estimate of slightly under 10% for th
